Abstract

In the experimental fieldon the autumn cabbage, Silviana variety of Vegetable Research and Development Station Bacău, four Lepidoptera species have been identified as major pests (Mamestra brassicae, Discestra trifolii, Pieris brassicae and Plutella xylostella) in 2019. Were collected biologic material represented by clutchs of eggs. In the laboratory, daily observations were made,to see the degree of parasitic attack. The highest density of parasitic Hymenopterawas recorded by T. evanescence at all M. brassicaeeggs.
